llPE-COUPLING.

Application filed July 27, 1531?.

To all whom it may concern Be it known that 1, JOHN F. Annrnson, a citizen of the United States, residing at Non way, in the county of Benton, State of Iowa,

have invented certain new anduseful improvements in Pipe-Couplings; and I do hereby declare the following to be a full, clear, and exact description oi the invention, such as will enable others skilled in the 5.0 art to which it appertains to make and use the same.

This invention relates to new and useful improvements in pipe couplings and particularly to devices for attaching nozzles to hoses.

One object of the present invention is to provide a device of this character which is simple in construction, effective in its operation, and which can. be quickly and easily coupled or uncoupled.

Another object is to provide a coupling which is capable of use'in connection with nozzles and with ordinary hose ends whereby a firm and effective joint is produced.

Another object is to provide a novel lock ing means for the coupling.

Other'objects and advantages will be apparent from the following description when taken in connection with. the accompanying drawing.

In the drawings:

Figure 1 is a vertical longitudinal sectional view through a nozzle and hose showing a portion of the coupling therefor.

F i 2 is an elevation of a pair of coupling meinfiers for connecting two hose ends together, and showing the locking device therefor. i Big. 3 is a. top plan view of the coupling locking device.

Fig. 4 is an enlarged vertical sectional view on the line 88 of Fig.

Referring particularly to the accompanying drawing 10 represents a hose end which is coupled to a nozzle 11 by means of my improved coupling device. Disposed in the hose end is a sleeve 12 the outer end of which is formed with an outwardly extending peripheral flange 13. The nozzle .11 has a 50 similar flange 14 on its inner end which is disposed in abutting relation to the flange of Specification of Letters Betent.

the sleeve. The flange oi the sleeve vided with a longitudinally extending t. inwardly turned lip 15 which is arranged to engage over and embrace a portion of the flange of the nozzle. This lip 15 extends around the flange 13 tonn'extent slightly less than one-half of"" the circumference of the flange, so that the flange of the non-- zle can be readily slipped in under the so lip and removed therefrom. A metal band 16 is engaged around the hose end, to clamp the same on the sleeve 12.

Mounted on one side of the sleeve 12 is longitudinally extending member 20:, and

ivotally connected to the end of this inem or, adjacent the flange. of the sleeve, is pair of links 21. Pivotally mounted between these. links is a member 22, the inner edge of which is formed with a notch uses which is of such dimensions as to snu. receive adjacent portions of ileum s the sleeve and nozzle, es at Piv. connected to the other end of themernher are the short links 24; which are connected by a transverse belt 25 bolt being erranged to engage in one or another of; series of notches 26 formed in the acent end oi the upper or outer edge of the men?- ber 20. lhus when the member 22 is swung so into position to grip the flanges, the links are swung downwardly so that the "colt 25 Incl.
